Introducing anthracene and amino groups into Ln-OFs for the photoreduction of Cr(vi) without additional photosensitizers or cocatalysts

Abstract

The stable LCUH-100 was designed and synthesized, by incorporating chromophores into lanthanide MOFs, as a high-efficiency photocatalyst, which can rapidly and efficiently reduce Cr(vi) under visible-light irradiation and has good cycle stability.

Four octamolybdate compounds with properties of organic dye adsorption and photocatalytic reduction of Cr(vi)

“…According to earlier reports, POM-based compounds can reduce Cr( vi ) to nontoxic Cr( iii ) by photocatalytic technology. 53,54 The title compounds were chosen as the catalysts in this study to facilitate the photocatalytic reduction of Cr( vi ) under a 300 W xenon lamp. The experiment was conducted in a 1.00 mM mixture of Cr( vi ) and C 2 H 5 OH solution.…”
